Leptogorgia hebes
''Leptogorgia hebes'', commonly known as the regal sea fan or false sea fan, is a species of soft coral in the family Gorgoniidae. It was formerly included in the genus ''Lophogorgia'' but that genus has been dismantled.〔(''Leptogorgia hebes '' ) Smithsonian Marine Station at Fort Pierce. Retrieved 2012-06-19.〕
==Description==
The regal sea fan is a colonial coral averaging about in height. It has a horny axial skeleton made of a fibrous protein called gorgonin covered with coenenchyme, a thin layer of living tissue from which the polyps protrude. Embedded in the coenenchyme are minute capstan-shaped and rod-shaped calcified sclerites. As well as strengthening the tissue, these are distasteful to most predators. The coral is densely branched but usually grows in a single plane. The colour varies and is usually some shade of red, orange or deep yellow but purple specimens occasionally occur. The skeleton is not rigid so the whole fan-like structure can sway with the movement of the surrounding water. The polyps are white and project in alternate rows from slit-shaped openings in hemispherical calyces on the branches. Each polyp can retract into its calyx and has eight pinnate tentacles and eight mesenteries dividing the body cavity. The whole colony has a single siphonoglyph, an opening through which water enters the structure.〔〔(''Leptogorgia hebes'' Verrill, 1869 ) South Carolina Department of Natural Resources.
